'A number that becomes negative when squared' is an imaginary number, which is used as part of the wave function that represents a pure state in quantum mechanics, which is a field of physics. It has ...

It may contain inaccuracies due to the limitations of machine translation. Humanities scholar Lee Eun-soo, professor of philosophy at Seoul National University (left), and mathematician Lee Seung-jae, ...

Mathematicians were disturbed, centuries ago, to find that calculating the properties of certain curves demanded the seemingly impossible: numbers that, when multiplied by themselves, turn negative.

If standard quantum theory holds up, imaginary numbers are critical. Imaginary numbers are necessary to accurately describe reality, two new studies have suggested. Imaginary numbers are what you get ...

To a nonmathematician, having the letter "i" represent a number that does not quite exist and is "imaginary" can be hard to wrap your head around. If you open your mind to this way of thinking, ...
